Zombies beware: Xbox One players are gunning for you in big numbers

Billions of zombies killed. Millions of miles driven. Microsoft says people have spent more than 50 million hours in games and entertainment on its newly released Xbox One gaming console.

The company best known for its Windows operating system said Tuesday the Xbox One is sold out at major retails and that its Xbox team and retailers are working around the clock to re-stock. But it said demand is far exceeding supply in the 13 countries where the gaming console has been launched.

"We are humbled and gratified by the overwhelming response from our fans to the launch of Xbox One," said Yusuf Mehdi, corporate vice president of strategy and marketing for Xbox. "Eleven days in, we are seeing record breaking sales and are selling every Xbox One we can make."

The company did not say how many units it has sold since the Xbox One's launch on Nov. 22, but it did release these killer stats:

• Over 3 billion zombies killed in "Dead Rising 3."

• Over 90 million miles driven in "Forza Motorsport 5" - equal to 3,673 trips around the world.

• Over 186 million enemies defeated in "Ryse: Son of Rome."

Sony Corp. reported Tuesday that it sold 2.1 million of its new gaming console, the PlayStation 4, as of Dec. 1, according to Bloomberg News. The PlayStation 4 hit store shelves Nov. 15.
